How to Write a Will: The Complete Guide

A will, or Last Will and Testament, can direct who receives probate property^[1] and name the person who will carry out those instructions^[6]. It can also address care for children under 18^[7], who get a guardian appointed by a court^[8]. Before drafting one, review the common estate-planning myths and identify which property a will can actually control.

A will doesn’t automatically govern every asset. Property may instead pass under a valid beneficiary designation, trust, transfer-on-death instrument, or form of ownership with survivorship rights. Spousal protections, creditor rights, taxes, court orders, interpretation disputes, and other law can also affect administration. Treat the will as one coordinated part of the plan, not a guarantee that every instruction will be followed exactly as written.

Writing a will comes down to six steps.

1. List what you own and what you owe. Include retirement accounts. Those generally go to the beneficiary you designated with the plan, under the plan's rules, so note who's named on each.^[5]
2. Decide who gets what. Name a backup for each gift in case someone dies before you.
3. Pick an executor. This is the person in charge of managing your estate after you die. Typical duties include paying debts and taxes and distributing what's left.^[6]
4. Name a guardian for kids under 18. A will can address care for children under 18.^[7] A guardian is appointed by a court, and the court has the final say.^[8]
5. Sign it the way your state requires. Witness and notary rules vary. The requirements section below covers them.
6. Tell someone where it is, and keep it current. Let someone you trust, like your executor or one of your family members, know where the signed original is. The National Institute on Aging suggests reviewing your plans at least once a year and after major life events, like a divorce or a move.^[7]

State law may permit a person to draft and sign a will without a lawyer. A form or online service can help organize information, but it can’t by itself guarantee that the document covers the right property, expresses the intended plan, or satisfies every execution rule.

State-qualified legal help is especially useful when:

• A dispute is possible. A blended family, estrangement, disinheritance, capacity concern, or coercion allegation can increase risk.
• Spousal or child rights may limit the plan. The protection and available choices vary by state.
• A beneficiary receives means-tested benefits. A direct inheritance can affect eligibility, and specialized planning may be appropriate.
• The plan includes a business, a trust, digital assets, foreign property, or real estate in more than one state.
• Tax exposure or ownership is unclear.
• The signing rules, form language, or effect of another document is unclear.

A limited consultation may also be available if full representation is unnecessary. Ask what the review includes and get the fee in writing. For broader cost considerations, read when legal help may be useful and what it can cost.

The cost depends on the document, state, provider, level of advice, and whether the plan includes other work.

• Self-prepared documents. A state form or template may have no purchase price, but there can still be printing, witness, notary, filing, storage, or review costs. The person using it remains responsible for choosing the right form and following current law.
• Online services. Prices and included features change^[2]. Compare whether the service includes state-specific documents, updates, attorney review, subscriptions, storage, and signing instructions. A generated document is still a draft until the applicable execution requirements are satisfied.
• Legal help. Fees vary by location, complexity, scope, and billing method. Ask whether the quote covers only a will or also powers of attorney, advance directives, trusts, funding work, tax advice, and later revisions.

Intestacy doesn’t create one predictable surcharge, and a valid will doesn’t eliminate every probate cost. Compare options based on the actual plan and written scope rather than a national price claim.

A holographic will is a handwritten will recognized under the law of some jurisdictions. The required handwriting, signature, material provisions, date, witnesses, and proof vary by state, and some states don’t recognize this form at all^[3][4]. Don’t assume that handwriting a document removes ordinary execution requirements.

When a state recognizes a holographic will, a court may need evidence about handwriting, intent, capacity, authenticity, or unclear language. Those proof questions can create risk, but no document type is automatically the easiest to challenge in every case. Confirm the current state rule and get qualified review when a witnessed document is available or the plan is anything but straightforward.

Will validity is state-specific. Common questions include whether the person has legal capacity and testamentary intent, what form of document is recognized, who must sign, how the signature must be made or acknowledged, how many witnesses are required, who’s eligible to witness, who must be present, and whether electronic or remote execution is allowed.

Notarization and a self-proving affidavit are separate issues in many jurisdictions, but their availability, wording, and effect also vary. A notary verifies a notarial act and doesn’t automatically make an otherwise defective will valid. Louisiana and other jurisdictions may use distinct document language or formalities. Use the current statute, approved court resources, and state-qualified legal help when the rule is unclear.

If a person dies without a valid will, state intestacy law determines who receives probate property and in what shares. The result depends on the state and family relationships. An unmarried partner, stepchild, friend, or organization may receive nothing unless another valid instrument or state law provides otherwise.

A court may also appoint a personal representative and, when needed, a guardian under state law. Intestacy doesn’t automatically make every estate longer or more expensive, and a will doesn’t automatically avoid probate. Timing and cost depend on the required procedure, property, claims, taxes, disputes, and local court process.

The options can include a state form, a self-prepared draft, an online service, limited-scope legal review, or full representation. The right level of help depends on state law, family structure, ownership, beneficiary designations, taxes, business interests, disability planning, conflict risk, and the person's ability to understand and complete the signing process.

Before choosing, ask what the form or service covers, whether advice is included, how updates work, what the current signing requirements are, and what happens when an answer doesn't fit the template. A lawyer can analyze issues and draft for the specific plan, but no professional can guarantee that every future dispute or administration problem will be avoided.

Five areas deserve a separate check:

1. Digital assets. Record accounts, lawful access plans, and preferences without placing passwords, seed phrases, or private keys in a will that may become public.
2. Specific personal property. Confirm whether state law recognizes a separate personal-property list and how it must be referenced, signed, or updated.
3. Contingent beneficiaries. State what should happen if a beneficiary dies first, disclaims, or can’t receive the gift, and coordinate this with beneficiary forms.
4. Pet care. Ask a willing caretaker, name a backup, and use a state-appropriate arrangement if money will be set aside. A pet is property under the law and can’t be appointed a human guardian.
5. Funeral and disposition wishes. Record preferences, but confirm who has legal authority and whether instructions in a will are controlling or may be found too late.

Start by listing assets, debts, beneficiaries, a proposed executor, and any guardian choices. Then choose the next step that fits your situation: use your state's current form for a simple estate, or speak with an estate attorney when the estate, family structure, property, taxes, business interests, digital assets, or state rules make the plan more complex. Confirm the state's signing, witness, notarization, self-proving affidavit, and electronic-will rules before execution.
